The scientific article presents experimental studies on the study of the biological features of growing plants of the genus Clematis L. An assessment of decorative qualities was carried out in order to determine the features of growing plants of the genus Clematis L. in the conditions of the city of Vinnytsia and the prospects of their use in landscaping. The eco-decorative value of the studied plants for urban landscaping is summarized. Taking into account the distribution of clematis in Eurasia, the genus Clematis has about 250 species, it is one of the most common in the family of clematis. According to the analysis of the results of the rooting of the cuttings, a high regeneration capacity of all studied taxa was established. The percentage of rooted cuttings ranged from 65 to 95% for all variants of the experiment. It was established that the highest percentage of rooted cuttings for the investigated cultivars was obtained after their treatment with succinic acid. And the best indicators of rooting are precisely for Clematis heracleifolia and is 97.2%, while the lowest indicator is for the cultivar Clematis jackmani "Perida" and was 83.7%. It was experimentally proven that the use of growth regulators led to a decrease in the length of the root system in Clematis jackmani "Perida", Clematis viticella "Josephine" and Clematis heracleifolia compared to the control. This effect was most pronounced in variants with use. For Clematis tibetana, an increase in root length was recorded in the version with succinic acid, but this difference was statistically insignificant. When studying the method of reproduction of luminos by seeds, it was established that stratification of the seed material is a mandatory aspect in this case, which significantly increases germination rates. Therefore, the percentage of germination for Clematis viticella "Minister" and Clematis jackmani "Sylvia Denny" cultivars in containers at a temperature of +25 °C is 75 and 80%, respectively, while in open soil – 25 and 30%, respectively, of the indicated cultivars. It has been experimentally confirmed that the species Clematis heracleifolia and Clematis integrifolia "Aljonushka" belong to the life form of chamephytes. The results of the conducted research indicate high winter hardiness of all studied species and varieties of lomonos in the conditions of the city of Vinnytsia, which was manifested in the preservation of the viability of regeneration buds. Clematis viticella "Minister", Clematis jackmani "Pink Passion" and Clematis heracleifolia demonstrated high drought tolerance during the growing season. Thus, the species of the genus lominosus adapt quite well to the variability of climatic conditions in the territory of the city of Vinnytsia, they respond normally to the aridity of the summer months. Such indicators are a guarantee of the high perspective of using these representatives in the system of greening and shaping the landscaping of this area.
